Two
Handsetsone base unit
A single cordless phone always ends up in the wrong room, and the ring you miss is invariably the one that mattered. This is a dual handset setup: two handsets that sit in different rooms — upstairs and down, or the shop floor and the back office — both synchronised to the same base unit, so you answer from whichever is closer. It also means you can switch between handsets without interrupting the call, and use one to call the other as an intercom. For an elderly parent, having a handset within reach in both the bedroom and the living room is genuinely worth more than any feature on the specification sheet.
144 hours of standby — and a landline that works when the mobile doesn't
Six days on standby and ten hours of talk time from rechargeable Ni-MH batteries means this is a phone you charge occasionally rather than nightly. That matters more than it sounds, because the reason to keep a landline in 2026 is dependability: it works when mobile signal is poor indoors, when a phone is lost or flat, and when someone needs to make a call without hunting for a charger. A cordless handset that's always ready, with long battery life and no frequent recharging, is the version of that which people actually use.
A large, readable display and a proper phonebook
The 1.8-inch alphanumeric LCD shows caller ID, time and notifications clearly — and the size is the point, because a phone in a family home is used by people of every age, including those who find a mobile screen difficult. With Caller ID you see who's calling before answering, which is the simplest defence against nuisance and spam calls. And the 100-entry phonebook stores frequently dialled numbers on the handset, so nobody has to remember or look up a number — you add, edit and delete entries as needed.

Advanced audio processing keeps voices clear and free of distortion — the thing a landline is still genuinely better at than a mobile indoors.
Press the base and the handsets ring — which solves the one problem every cordless phone owner has had at least once.
Mount the base on a wall in a hallway, kitchen or behind a shop counter instead of giving up surface space to it.

Dual Handset Setup
The dual handset setup includes two handsets that can be placed in different rooms, ensuring that users can conveniently receive incoming calls from whichever handset is closer to them. This setup enhances accessibility and ensures that users never miss important calls, even when moving between different areas of their home or workplace. With each handset synchronised to the same base unit, users can seamlessly switch between handsets without any interruption in communication.
Handset Locator
The hands-free speakerphone functionality allows users to engage in conversations without holding the handset, enabling multitasking and hands-free operation. This feature is particularly useful for situations where users need to take notes, access documents, or perform other tasks while on a call. With clear audio output and built-in microphone, the speakerphone ensures that both parties can communicate effectively without the need for a handset.
Large LCD Display
Featuring a large LCD display with a 1.8 inch alphanumeric display, this phone provides clear and easily readable information, including caller IDs, time, and other important notifications. The spacious display enhances user experience by ensuring that information is presented in a legible and visually appealing manner. Whether it's checking caller details or navigating through menu options, the large LCD display offers convenience and accessibility for users of all ages.
